Comparison Of Postoperative Analgesia Effects Between Suprainguinal Fascia Iliaca Compartment Block And Pericapsular Nerve Block Combined With Lateral Femoral Cutaneous Nerve Block On Hip Surgery

Objective:To compare the effect of suprainguinal fascia iliaca compartment block and pericapsular nerve block combined with lateral femoral cutaneous nerve block on block range,analgesia and motor function after hip surgery.Methods:Sixty patients undergoing hip surgery in our hospital from October 2021 to December 2021 were included.They were randomly selected and divided into group S and group P with 30 cases in each group.After awakening from general anesthesia,group S was under ultrasound-guided suprainguinal fascia iliaca compartment block,while group P was under pericapsular nerve block combined with lateral femoral cutaneous nerve block in the Post-anesthesia care unit（PACU）.Then the NRS scores of resting pain in the PACU,resting and motor pain at 1,6,12,24 and 48 hours after block,the range of sensory block within 30 minutes,the number of analgesia pump compressions and the cumulative dosage of sufentanil,and the patients’ analgesic satisfaction score within 24 and 48 hours after block were recorded.The grading of quadriceps femoris strength and adductor strength were recorded at 1,6,12,24 and48 hours after block.The length of hospital stay,postoperative nausea and vomiting,dizziness,infection of puncture site and other adverse reactions were also recorded.Results:There were no significant differences between group P and group S for NRS scores of resting and motor pain at 1h,6h,12 h,24h and 48 h after the block,the cumulative dosage of sufentanil,the number of analgesia pump compressions,the patients’ analgesic satisfaction score at 24 h and 48 h after the block and the length of hospital stay（P>0.05）.The NRS score of resting pain at each time point after block was lower than that in PACU（P<0.05）.However,the P group significantly reduced the sensory block on the front and medial side of the thigh（P<0.05）,and the incidence of quadriceps and adductor block was also significantly reduced at 1h and6 h after the block（P<0.05）.Conclusion:Pericapsular nerve block combined with lateral femoral cutaneous nerve block has a good postoperative analgesia effect for hip surgery,and can preserve the patient’s motor function and reduce the sensory block,which is conducive to the early postoperative activity and rehabilitation,and can be used as a new choice of postoperative multimodal analgesia.
